Use of unload event

[yurtsiv]

Hocuposucs provider uses unload event which is not very reliable.

Was it a deliberate choice or have you just not had a chance to try visibilitychange as an alternative?

Thanks!

hey @yurtsiv, thanks for raising this! I don't think it was a deliberate choice.

We're just using this to remove awareness, which, in case the event does not fire, will happen after the provider was absent for 30 seconds, so it's probably not a big issue. Won't hurt to switch to visibilitychange, so feel free to open a PR if you are interested in the change :)
